10% on the first trading day, another 35% after FY26 results, then the remainder after Q1'27 results or Day 180, whichever comes first.
ANTHROPIC IPO · SUPPLY PRESSURE
The unlock is fast.
Will price react?
Tracking sale eligibility in Anthropic's S-1 alongside ANTH and SpaceX HIP-3 market data.
BOTTOM LINE
A valid supply-pressure calendar—but not yet a model of actual selling.
Anthropic's founders may release up to 29% of their locked shares at Day 180, while ordinary 180-day holders begin releasing shares much earlier. The draft S-1 still leaves absolute share counts blank, so we know when shares become eligible, but not how much supply may reach the market.
MARKET TAPE
How did the two pre-IPO markets move?
io:ANTH xyz:SPCXCommon start = 100 · absolute prices are not comparable across different contract units
LOCK-UP MAP
When does each cohort become eligible to sell?
Percentages refer to each cohort's pre-IPO locked holdings, not total shares outstanding.
180-day holders
Day 76 · 26%Staggered early releases
Releases begin on Days 27, 48, 62 and 76, followed by biweekly tranches after FY26 results. Up to 86% may be eligible before Day 180.
Founders
Day 180 · 29%Earlier first release than SpaceX
The solid Anthropic line is verified from its S-1. The dotted SpaceX line is a secondary benchmark from the source chart and remains unverified against a primary filing.

WHAT TO WATCH IN PRICE
Four signals that matter more than the date
- ANTH relative return — does it underperform SPCX and the broader market?
- OI and volume — are new positions building as price falls?
- Funding — persistent short crowding or a temporary hedge?
- Absolute share counts — does the final prospectus support a defensible dollar-overhang estimate?
INTERPRETATION LIMITS
Eligible to sell ≠ actual selling
A lock-up is a private agreement with the underwriters. Expiration creates the right to transfer; it does not prove a sale. RSU vesting, 10b5-1 plans, tax withholding and each holder's liquidity needs are separate questions.
These HIP-3 prices come from derivative markets operated by different deployers. They are not spot shares and do not represent directly comparable units of enterprise value.
